This oven baked 3-ingredient chicken is the kind of practical, crowd-feeding dinner that never really goes out of style. It leans on a few pantry and freezer staples to turn chicken into a cozy, gravy-rich main dish with almost no prep, which is exactly why recipes like this became church-supper and Sunday-dinner favorites for decades. If you need something easy enough for a busy weeknight but comforting enough for company, this is one of those back-pocket meals worth keeping.
Serve this chicken over mashed potatoes, white rice, egg noodles, or even thick slices of toast so none of the savory onion gravy goes to waste. A simple green bean side, buttered corn, roasted carrots, or a crisp side salad balances the richness nicely, and if you're feeding a bigger group, a basket of warm rolls makes it stretch even further.
Oven Baked 3-Ingredient Chicken
Servings: 6 to 8
Ingredients
8 bone-in, skin-on chicken thighs
1 large yellow onion, thinly sliced
2 packets dry brown gravy mix
Directions
1. Preheat the oven to 350°F and lightly grease a large 9x13-inch baking dish or blue speckled enamel casserole dish.
2. Spread the sliced onion evenly across the bottom of the dish, then arrange the chicken thighs on top in a single layer.
3. Sprinkle the dry brown gravy mix evenly over the chicken and onions so everything is well coated.
4. Cover the dish tightly with foil and bake for 45 minutes. Remove the foil, spoon some of the developing juices over the chicken, and continue baking for 25 to 35 minutes more, until the chicken is tender and cooked through and the onions are deeply softened.
5. Let the chicken rest for 5 minutes before serving, then spoon the onion gravy over each portion.
Variations & Tips
Use boneless chicken: Boneless skinless thighs work well if that is what you have on hand. Start checking a little earlier since they usually cook faster and can dry out if left too long.
Add a little liquid if needed: Some gravy mixes are saltier or thicker than others. If the pan looks dry during baking, add 1/4 to 1/2 cup water so the onions can soften into a spoonable gravy.
Make it ahead: You can assemble the dish a few hours in advance, cover, and refrigerate it until dinner. This is especially helpful when you're juggling work, errands, or hosting family on a weekend.
Serve it over starch: The best part of this recipe is the savory gravy at the bottom of the pan, so plan on mashed potatoes, rice, or noodles to soak it up.
